Since you mention you are on a pretty tight budget do you think this should be an area to be consider shrinking? IMO price/performance ratio of H50 is.... not so good... and using it on a review? Not only this is an entry pre-assemble kit but I am not entirely sure is that a good option especially H-50's recommend setup is to blow air "into" the case.
And did I miss something? you wrote 500 as budget but just the cpu and mobo is around 400? so 100 for ram psu case???
EDIT: oh btw if you decided to go ahead for H50 be sure to order your 1156 mounting kit from corsair... took me almost 1 month and a few bucks to arrive
got forced to pick up that CNPS10 since the mounting kit took so long
